Bisphenol-A is an organic molecule often referred to in both the scientific and popular media. Its structure looks like this:
Its CA Index Name (the official name assigned to the structure according to Chemical Abstracts nomenclature rules) is
Phenol, 4,4'-(1-methylethylidene)bis-which doesn't exactly roll off the tongue! It's easy to see why people would rarely use this name in conversation, media, or even in a technical paper. So Bisphenol-A or BPA are more often used as verbal shorthand for this compound.
Fortunately, Chemical Abstracts Service provides a good alternative to names with the CAS Registry Number, which stands in as an unambiguous search term in many kinds of scientific databases.
The Registry Number for BPA is 80-05-7. Use this number instead of its name when you search in a chemical database such as SciFinder, and you'll get much better results.
